CURSES(3) NetBSD Programmer's Manual CURSES(3)
NAME
curses - screen functions with ``optimal'' cursor motion
LIBRARY
Curses Library (libcurses, -lcurses)
SYNOPSIS
cc [flags] files -lcurses -ltermcap [libraries]
DESCRIPTION
These routines give the user a method of updating screens with reasonable optimization. They keep an image of the current screen, and the user sets up an image of a new one. Then the refresh() tells the routines to make the current screen look like the new one. In order to initialize the routines, the routine initscr() must be called before any of the oth- er routines that deal with windows and screens are used. The routine endwin() should be called before exiting.
